function [y] = noise(x)
% noise(x)
% 	Parameters:
% 		x:	a time series 
% 
% 	Outputs:
% 		y	the time series
% 
% 	Purpose of this code:  This code is designed to generate a sequence of values equal in number to 
% 	a given time series chosen randomly from a set that is normally distributed with a mean of 0 and 
% 	a variance of 1.
